我在这方面花了很多时间,这显然超出了我的新手理解/技能。我尝试安装 django-heroku-memcacheify使用 pip install,这会引发错误。我将问题追溯到 pylibmc ,这导致了所有问题。这是错误日志中有趣的部分之一:

_pylibmcmodule.h:42:36: 错误: libmemcached/memcached.h: 没有那个文件或
目录


这是(几乎)完整的回溯:

所以这是交易

我无法在我的本地环境 b/c 中测试它,我在 Windows 上运行。但从我读过的 libmemcachedalready installed在heroku上。其他人似乎对 pylibmc 没有任何问题,因为我在谷歌上找不到任何东西。 In this post他们在谈论:

that if they detect that you are loading pylibmc, they will bootstrap libmemcached for you



这可能是问题所在,要么未提供,要么路径错误。任何帮助表示赞赏!如果这不起作用,我将不得不使用Redis,这似乎要困难得多......不知道我是否足够先进。

编辑
可能无关紧要,但我使用的是带有 init 的设置文件夹,而不是 settings.py 文件。我听说这会导致一些奇怪的行为,因为 heroku 并不总是记得这是可能的。

编辑 2

由于有数百人在 heroku 上运行 memcached 和 django 没有任何问题,我认为 heroku 用户不应该使用某种 hack 安装 libmemcached。当 heroku 在您的需求文件中检测到 pylibmc 时,文档会谈论它,好像它是为您引导的。这使我得出结论: A) 我的设置或我使用的应用程序之一有问题,或者 B) heroku 最近改变了一些东西,破坏了 Django 的 libmemcached 的自动引导。我尝试使用 heroku 配置进行全新安装:添加 CLEAN_VIRTUALENV=true 但 that's not working either right now .我希望它是 一个 有人遇到了同样的问题。如果是 我不知道如何解决它。

最佳答案

我已经与 Heroku 的友好人士交谈过,似乎我的 requirements.txt 设置造成了所有破坏。不要在 root 中使用从另一个需求文件导入的需求文件!至少对于 pylibmc 不起作用,因为如果根需求文件中没有与 pylibmc 的显式行,则 libmemcached 不会被引导。我希望这会帮助其他人避免浪费我在这个问题上花费的 10 个小时。好极了!
